Double world champion, "Killer Queen" Susi Kentikian promises a tough fight against her rival Julia Sahin.

"Of course I know Julia Sahin well, her fighting style is very well known. She is the undefeated champion in a lower weight class, very agile and quick, but I am too. And I punch harder. Even if you can't guarantee a KO, I will live up to my nickname 'Killer Queen.' My preparation has been and will still be very intense in the coming weeks. It will be a very tough fight!"

Kentikian and Sahin will compete in a world boxing championship flyweight title fight in Rostock on Saturday, Oct. 10.
